A young koi is about 3-7 inches. when they grow to adulthood, they can as long as 40 inches!
Koi are a large growing fish (I've seen them at over 50cm long) and so they require a pond not an aquarium. They are also quite expensive. Koi are not for the beginner.

A Koi should grow around 6 to 8 inches long in its first year. By age 3 it should be about 24 inches long. I guess that's a reasonable growth rate
The age of a koi fish that is 5 inches long can vary significantly depending on its growth conditions, such as water quality, diet, and environment. Typically, koi can grow about 1 inch per year during their early years, so a 5-inch koi might be around 1 to 5 years old. However, some koi can grow faster or slower, making precise age estimation difficult without additional context.
A member of the Koi Koi tribe is often referred to as a "Koi Koi" or a "Koi." The Koi Koi are indigenous people of Namibia, primarily known for their distinctive cultural practices and semi-nomadic lifestyle. They are part of the larger Khoisan ethnic group, which is renowned for its unique languages and traditions.
Koi is a type of fish. Just don't put koi in the pond and it will not be a koi pond.
If the Koi is large enough it may well eat a goldfish fry but Goldfish and Koi are not fighting type fish so they do not normally bite one another.
